6.17. DEBUG commands

Debug commands show advanced diagnostic about Abilis CPX system and resources. These types of commands need administrator or super user rights.

[Note]Note

Shown information is strictly technical and meaningless to the user; Abilis CPX technicians could need it for detecting and solving eventual problems.

By typing the following command, it's possible to display the syntax.

[13:54:30] ABILIS_CPX:debug ?

6.17.2. DEBUG RES

This command shows debugging information about the specified resource. By typing the following command, it's possible to display the command syntax.

[13:54:40] ABILIS_CPX:debug res: ?

DEBUG RES:A [par:val]              Display debug information of all resource(s)
DEBUG RES:type [par:val]           Display debug information of all resource(s)
                                   of the specified type.
DEBUG RES:type-n[,...] [par:val]   Display debug information of the specified
                                   resource(s)

Additional parameters:

LAYER:     Select resource lower layer [L2, LINK, IP, IPT, PPP, PPPOE]
           Mandatory for IP and PV resources, otherwise optional.
                                                  <Only if PROT: not specified>
PROT:      Select protocol layer [LAPB, MLM, ML, PLINKE, PPP, POECLI]
           Mandatory for IP and PV resources, otherwise optional.
                                                 <Only if LAYER: not specified>
SIZE:      Select debug buffer size [7..63 Kibyte].
           By default 63 Kibyte.                                     <Optional>
LSN:       Lsn value [0..65534(dec) or 0000..0FFFE(hex), A]          <Optional>
CMD:       Command string. Spaces require double quotes
           (e.g. CMD:"str1 str2 ...")                                <Optional>

Data are stored in a 6 KB size buffer. Depending on the resource type, where the command is executed on, this buffer could not be enough and at the end of the visualization the following message will be displayed “INCOMPLETE INFORMATION: BUFFER SIZE TOO SHORT”. By using the option SIZE, the user can eventually increase the maximum buffer size used by the command. The indicated value (in KB) must be in the interval [7 - 63].

By using the options LSN and CMD it's possible to select the type of debugging information to be displayed.

For example, to show debugging information of an ADSL line, type the command debug res:ip-xx prot:ppp, where xx is the number of the IP resource associated with the ADSL line. With the options LSN, it's possible to select the type of debugging information to be displayed; if it's set to 0, it will be displayed the command help.

6.17.3. DEBUG SIMULATE EVENT

The command DEBUG SIMULATE EVENT:val simulates an event for debugging purposes. Use the following command to show all possible events:

[13:58:50] ABILIS_CPX:debug simulate event: ?

DEBUG SIMULATE EVENT:val [opt:val]     Simulate an event for debugging purposes

Possible events:

XCP [CPU:val]  Structured exception on the specified CPU [MAIN or EXTRA].
               The CPU specification is optional. By default the exception
               is simulated on the Main CPU (corresponding to CPU:MAIN).
WDL            WDLIVE1 event. It executes a never ending thread loop with
               IRQ MONITOR RESTART disabled.
LOOP [msec]    It executes a thread loop without task switching for the
               specified interval [1..2000 ms].
               If 'msec' is omitted the loop is without time limit.
IRQLOOP        Requires at least one ETH resource running and
               'MULTI-CPU' mode DISABLED.
               It forces the interrupt generation while serving is disabled.
               This condition causes an IRQ LOOP which has to be solved by
               IRQ MONITOR.
WDGRESET       WDG Reset. It resets WDG but doesn't make SW reset of the PC.
               If the WDG reset has no effect, after 15 sec a SW reboot
               is executed.
SWRESET        Software only reset
BLOCKAGE [msec]  Complete lock. It disables ALL the interrupts and executes
               a loop without task switching for the specified time
               interval [1..2000 ms].
               If 'msec' is omitted the loop is without time limit.
TSAVE          Automatic TRACE saving request (trace stop-save-start)
QUIT           Quit exception
TASKOVR        Tasks overflow, i.e. too many threads
HOVR           Heap overflow (bad allocation exception

6.17.3.1. DEBUG SIMULATE EVENT:XCP

6.17.3.3. DEBUG SIMULATE EVENT:WDGRESET

This command resets WDG but doesn't make Abilis SW reset. It's useful to verify if the watchdog (MFIDE/MFPCI/MFLPC) is really able to make a HW reset of the Abilis CPX, and thus if the reset cable is properly connected.

[14:03:16] ABILIS_CPX:debug simulate event:wdgreset

YOU ASKED TO SIMULATE THE 'WDG RESET' EVENT.
THIS WILL CAUSE THE SYSTEM TO BE RESTARTED, PROCEED ANYWAY (N/Y)?y

PROCEEDING WITH WDG RESET EVENT SIMULATION...

The log shows the following information after using this command:

If the reset does not take place, the only way to restart Abilis is using the warm start command:

[14:09:59] ABILIS_CPX:debug simulate event:wdgreset
